CHARLES T. SCHOE'N, OF PHILADELPHIA, PENNSYLVANIA.

CENTER-BEARING PLATE FOR RAILWAY-CARS.

SPECIFICATION formmg part of Letters Patent No. 408,757, dated August 13, 1889. Application filed June 13, 1889. Serial No. 314,135. (No modehl To all whom it may concern:

Be it known that I, CHARLES T. SCHOEN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Center- Bearing Plates for Railway-Oars, of which the following is a full, clear, and exact description.

This invention relates tocenter-bearing plates of wrought metal for railway-cars; and the object of the invention is to facilitate the interchangeability of such wrought-metal bearing-plates with the ordinary cast-metal bearing-plates in common use.

The invention consists in wrought-metal center-bearing plates having interposed bearing-rings, the plates being constructed by preference of steel plate pressed to shape and the bearing-rings being cast malleable or wrought, and all being constructed and arranged substantially as I will proceed now particularly to set forth and finally claim.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1 is a plan of one of the plates. Fig. 2 is a longitudinal section of the plates and rings united. Fig. 3 is a crosssection, and Fig. 4is a plan, of one plate; and Fig. 5 is a longitudinal section of centerbearing interchangeable with the Pennsylvania Railroad Companys standard.

The illustrations and the following description will suffice to set forth the principle of my invention, and it is necessary only to add that the invention is applicable to other standards by obvious mechanical changes, without, however, by this statement excluding the possible patentability of future improvements.

Referring now to Figs. 1, 2, and 3,the plate a is made with radial ribs 1) to stiifen it. Its sides 0 are flanged to embrace the car-timbers, and said plate is provided with a central circular rib d for stiffening purposes and to receive and confine the bearing-ring. The usual central opening e is made, and it is provided with a flange f. These essential features are common to the upper and lower bearing-plates, and these plates diifer mainly only in their adaptation to the parts to which they are applied.

The bearing-rings g are made in two sections h and 2', each substantially rectangular in cross-sectional outline. The section 71 has its base laid in the trough of the upper plate between the rib d and the flange f, and the flange is turned over upon the base to confine it in place. Similarly the base of sectionz' is laid in the trough of the lower plate between the rib d and the flange f, and the flange is turned over upon it for a like purpose. The upright portion of the section '6 is fitted to the face of the base of section h and its side adjacent to the depending upright of the section h, the two sections bearing one upon the other.

In some cases there would be more than one set of bearing-rings, and they would be of dilferent diameters. In interchanging with cast-iron center-bearing plates the differences in thickness between the cast iron and steel may be compensated for by varying the thickness of the bearing-rings, measuring from the bearing-surfaces of the rings to the outside of the plates.

In Figs. 4 and 5 there are two annular ribs d and cl and a central opening 6 in each plate. The ring-sections h and i are made with lugs 2, passed through openings 6 in the trough, which lugs are upset or clinched to holdthe ring-sections in place in addition to the overturned flanges f; but, instead of these ring-sections taking the burden, I keep them normally separated-and utilize them for resisting concussion or blow in use. The outer rings take the burden, and these are constructed thus: The upper plate-bearing ring-section k is mounted upon or straddles the outer rib cl, and is provided with studs or dowels 7c, projecting through the plate to assist 'in holding the plate in place under the car, although these studs or dowels may be replaced by paps struck up from the plates themselves. The section may be riveted to the plate by rivets or lugs k (See Fig. 4.) The lower section Z of the ring is also fitted to the rib d; on the lower plate, and is provided with studs or dowels Z, which, as in the case of the upper plate, may be replaced by paps struck up from the lower plate. The section Z is riveted to the lower plate by rivets or lugs 1 The said section Zis made with a trough, if desired, to receive the bearingface of the upper section.

The ring-sections in Figs. 1, 2, and 3 may be riveted to the plates, as just described.

hat I claim is 1. lVrought-metal bearing-plates having two-part bearing-rings interposed between them and held in place, substantially as described.

2. Pressed-steel bearing-plates having annular ribs and central flanged openings, combined with rings arranged between the ribs and flanged openings, the flanges of said openings being turned over upon said rings to hold them in place, substantially as described.

3. Center-bearing plates of wrought metal having strengthening-ribs and central flanged openings, combined with two-part rings held in place between the ribs by the overturned flanges of the central openings and riveted or clinched lugs, substantially as described.

4. The bearing-plates, the two-part outer bearing-ring secured thereto, and the twopart central ring, also secured to the plates and adapted to resist concussion, substantially as described.

5. The bearing-plates provided with ribs, combined with a two-part bearing-ring, one part of which ring is provided with a trough to receive the other, substantially as described.

G. The bearing-plates provided with ribs, combined with a bearing-ring made in two sections, each section applied to the rib of its plate by straddling the 'same, substantially as described.

7. Inner and outer rings made in sections fitted to one another, substantially as described, combined with bearing-plates, to which said sections are secured, substantially as set forth.

In testimony whereof I have hereunto set my hand this llth day of June, A. D. 1889.
